How many people are having problems with Google Calendar not working for the whole day today? I can't log into Calendar using my primary account (Server Error – Google Calendar is temporarily unavailable. Please try back later) but it works fine on my secondary account.

Ah, and the link to the discussion group (google.com/support/forum/p/Cal ...) is dead, but several people are complaining in the forums: google.com/support/forum/p/Cal ...

Works fine here at the moment. I had no problems today.

My Google Calendar will not allow me to assign an event to a different calendar unless my own access has been set to manage editing only. If I have sharing added, the calendar won't even show up in the list of available calendars in the Event Details view. And I've created all of these calendars.
